P460QL2 Vessel Plate A516GR70

A516GR70 steel is a carbon steel plate widely used in pressure vessel and boiler manufacturing. "A516" is a steel standard code designated by the American Society for Testing and Materials (ASTM), which is specially used for the manufacture of carbon steel plates for pressure vessels; "GR70" represents the grade of this steel (Grade 70), indicating that its tensile strength is 485-620 MPa, and its yield strength is not less than 260 MPa, which is higher than other lower grades (such as Grade 55 or Grade 60). Its chemical composition includes carbon (about 0.27%), manganese, silicon, sulfur and phosphorus, and has good ductility and weldability.

High Strength
The tensile strength range of A516GR70 steel plate is 485-620 MPa, and the yield strength is not less than 260 MPa. The material remains stable at pressures up to 100 bar, ensuring equipment safety.

Good Low Temperature Toughness
The average impact energy of the A516GR70 steel plate at -40°C is 27 J, which means that the average energy required for the material to resist impact damage is 27 Joules. This low-temperature toughness makes it suitable for equipment that needs to operate in extremely cold environments, such as cryogenic storage tanks and liquefied natural gas containers. It can effectively prevent sudden fracture of the material and ensure the stability of the equipment.

Good Weldability
The sulfur content of A516GR70 steel plate is less than 0.03% and the phosphorus content is less than 0.035%, which significantly improves the welding performance of the material, making the tensile strength of the weld reach 500 MPa. Its welding properties make the material popular in the manufacture of petrochemical equipment, pressure vessels and large industrial boilers, significantly reducing welding defects during the production process.

Good Corrosion Resistance
A516GR70 steel plate has excellent corrosion resistance. Its corrosion rate in 5% sulfuric acid solution is less than 0.1 mm/year, which is significantly better than ordinary carbon steel. This feature makes it particularly suitable for equipment that requires long-term storage of corrosive media such as petrochemical and energy sources, reducing the frequency of equipment maintenance and replacement.

Pressure Vessel Manufacturing
A516GR70 steel plates are widely used to manufacture various pressure vessels for storing liquids and gases, such as storage tanks and reactors in the petroleum, chemical and natural gas industries.

Boiler Equipment
This steel plate is often used to manufacture the outer shell and internal components of industrial boilers.

Cryogenic Storage Tanks
A516GR70 steel plates are suitable for manufacturing equipment in low-temperature environments such as liquefied natural gas (LNG) storage tanks, liquid oxygen and liquid nitrogen storage tanks, and can withstand shock and pressure changes under extremely cold conditions.

Heat Exchange Equipment
In the chemical and energy industries, A516GR70 steel plates are often used to manufacture shells and tube sheets of heat exchangers.

Energy Equipment
This steel plate is widely used in energy equipment such as nuclear power plants and thermal power plants. It is used to manufacture core equipment that withstands high pressure and high temperature, such as steam generators and reactor vessels, and can meet extremely high safety requirements.

Chemical Equipment
The corrosion resistance of A516GR70 steel plates makes it particularly suitable for storage tanks and separators in the petrochemical field. It can resist corrosion from acidic or neutral media for a long time and reduce equipment maintenance costs.
